I bet you if you're bored one day, lie down and think of one thing that you used to love to do.
Dressing yourself up?
gift wrapping random objects?
Riding a bike?
And just do it.
Just do it, because you love it, you will be good at it.
If you haven't done it for too long.
Start from the beginning. You will remember how to do what you used to love to do.
