I second this "just show up" mentality.

Putting too much pressure on oneself to do too much, especially in the beginning before the body has had time to adapt to the pressures of training, is a recipe for burnout.

On the other hand, a slow start, "just keeping showing up, do a little, give yourself plenty of time and space to rest" mentality, in the long run, leads to better performance.

Slow and steady wins the race.
