If it's still a struggle to get more out of life, may we suggest you listen to our ancestors who coined the term. Seize the Day. Enjoy the moment. Don't keep waiting for the right day or the right weekend or the right activity. The same applies even more so to play and recreation.
Life is short and the good times are fleeting.
So just seize your play opportunities right now. Do it because it's good for you. Do it because it's fun, but just do it now.
