Some people love playing squash. You can hit the ball as hard as you like every time and even at a basic level have a pretty good chance of it staying in play. It’s a short, sharp, fast game and provides an intense workout.
Other people love playing electric guitar. You can play loud (as loud as you want if you have no neighbours), and even at a basic level play enough chords to sound like some pretty famous guitarists and bands.
It’s a different story if you take up tennis, or for that matter the trumpet or violin. At the beginning you will hit the ball into the net or out of play as often as you’ll hit it in, and play a lot of squeaky notes before you hear the sound you’re hoping for.
Results can take different lengths of time to arrive depending on the discipline. If you’re starting something new this January or at any time, remember that and keep at it.
