Record yourself playing, even the simple songs. Someday someone you love will want to hear you again.

A recording of somebody playing badly is worth more later than a flawless one by a stranger. Your own standards are the obstacle here. You hear a simple song and a mistake in the fourth bar, while somebody who loves you hears you, which is an entirely different thing to be listening to. Quality is close to irrelevant to the people who will want it.

Record one song on your phone this week with no retakes, however simple it is, and keep it somewhere it will not get deleted. Add the date. Do it again every few months so there is a run of them.
