Practice

Body and mind are tools. You are their creator. You decide.
It's an expansive wide 'universe.' You-in-verse. Your verse.

'Association'. Act of connection. See and duplicate. Reflection.
It is also the creation of what you want, to be reflected. 
'Practice makes perfect' works.

Have started some new things lately. First time and maybe second, are hard. 
Third time the new, has begun to be regular. A habit.
If it's a physical thing, the body too, gets used to the do.
Muscles tighten and also gain the memory.

Keep it simple. Don't push it. Start at a low gradient.
Listen (feel) the changes and adapt accordingly. 
​Rewardingly.
