I wish I had this energy again. I've got a list of side projects to get on with. I've made little progress in the last year, and suspect its burn out to blame - I'm just constantly exhausted. I think if you have the energy, this is awesome fun. It might even get to the point where one of them makes some decent income. But if you don't, like me, just realise that there is a reason for that, and it's OK. You need rest…
totally feel you, I also have a list of projects I wanted to jump in, but I feel exhausted, and blame myself for not working on them.
[Comedy take: I blame you for my projects not being done too! :) Bada-tish!]
Seriously though, guilt, blame, shame all that stuff: it's not helpful. It just compounds the feelings that make it hard to get started again because those feelings are emotionally draining.
What I'm trying to get myself into the habit of is a 5-minute dip into something. If I just say to myself when I'm feeling slightly exhausted "I just need to put 5 minutes into this next task, and then I'll stop", I frequently find myself spending 30+ minutes on it. I can then feel a sense of over-meeting my "goal". That builds a little momentum, it makes you feel good about getting something done.
I also have reminded myself of the advice I gave others when younger: don't underestimate rest - particularly sleep, but also generally doing nothing - as being part of getting stuff done.
I don't do this well at all at the moment, hence my comment you're replying to, but I absolutely 100% will not let blaming myself get into my head like that, and that does help a little with the 5-minute trick.
