The fear of failure holds many back from acting however I don't agree with it. Failure can be motivating and it certainly provides valuable lessons, information and options on how to evaluate and push on...Even if that's failing to hike or walk.

One needs discipline to apply discipline but it's that which helps to get things done. Think I'd yourself and what you've done to move your current DP project forward; a lot of discipline I'd say.

If we deal with the little things that get in our way, often easily dealt with, then those bigger things don't see as large or, at least, we have more ability to deal with them.

Anyway, go for a walk, you may find it'll help you sleep better. That's my motivational speech. Lol.
