So juggling is something beneficial and to master, the skill WILL greatly enhance your game.  

HOW TO JUGGLE LIKE A BOSS (Video)

LEVEL 1 - (All players start here).
Player drops the ball and touches it once with the foot they prefer. The ball bounces, only once, then touches with their foot again, then the ball bounces, the player touches with their foot, the ball bounces and so on. If the ball bounces more than once on the floor then the counting starts again.

For Level 1, either foot may be used anywhere within the touch cycle. So that the pattern goes like this:

foot - bounce - foot - bounce - foot - bounce - foot - bounce - etc.

50 consecutive touches completes this level.

(Hints: visualize the “bottom flat” of the ball. Keep the foot straight with the big toe pointing down so that the foot presents a flat surface and the ball strikes cleanly. Strike flat level surface of your foot precisely to the “bottom flat” of the ball)

LEVEL 2 - (For those who have completed Level 1).
This exercise is very similar to the previous one but this time the player touches the ball 3 times with his stronger foot and lets the ball bounce on the ground and then touches once with his weaker foot and lets the ball bounce (this completes one round). So that the pattern goes like this (assuming your right foot is your strong foot):

right foot - right foot - right foot - bounce - left foot - bounce (one round) - right foot - right foot - right foot - bounce - left foot - bounce (two rounds) - right foot - right foot - right foot - bounce - left foot - bounce (three round3) - right foot - right foot - right foot - bounce - left foot - bounce (four rounds) - etc.

(Remember that the sequence is always 3 touches with the stronger foot, bounce, 1 touch with the weaker foot, bounce (1 round), 3 touches with the stronger foot, bounce, 1 touch with the weaker foot, bounce (2 rounds) etc.)

25 rounds completes this level.

LEVEL 3 - (For those who have mastered Level 2).
The player starts with the ball in his hands. He throws it into the air and with his INSTEP (the INSTEP is the SHOELACE portion of your foot; not to be confused with the inside of your foot) returns it to his hands. He repeats this with his weaker foot, then with both thighs and lastly with his head and always returning it to his hands after each touch.The sequence then is:

hands - instep - hands - other instep - hands - thigh - hands - other thigh - hands - head – hands (one round)

25 rounds completes this level.

LEVEL 4 - (for those who have completed Level 3).
In principle, the exercise is the same as the one in Level 3 except this time there are 3 touches with the stronger foot, one with the weaker, 3 with each thigh and 2 with the head.

The sequence then is:

hands - r. instep - r. instep - r. instep - hands - l. instep - hands - r. thigh - r. thigh - r. thigh - hands - l. thigh - l. thigh - l. thigh - hands - head - head - hands (one round)

25 consecutive rounds completes this level.

LEVEL 5 - EXCELLENCE(for those who have completed Level 4).
The same sequence that was started in Level 3 but this time we increase the number of touches for each round.
For Example:
Hands, instep, hands, other instep, hands, thigh, hands, other thigh, hands, head (one round);
hands, 2 touches with the instep, hands, 2 touches with the other instep, hands, 2 touches with thigh, hands, 2 touches with other thigh, hands, 2 touches with head (2 rounds);
3 touches with each surface for round 3 and so on up to 20 rounds. If the sequence is broken or the ball falls to the ground you start again from the beginning.

Congratulations! You have now mastered quality touch on the ball!

With this kind of touch quality, you are probably already better than 99% of players your age. And with this kind of touch quality, there is no other soccer skill you cannot learn. You have laid the foundation for every dribbling move, every kind of shot & pass, and every collection method this sport has to offer.
