I agree that developing "lifehacks", when taken too far, can be a form of procrastination itself. ...and that the underlying cause is emotional.
Nevertheless - we still need to do them.
I think the answer is both simpler and more difficult than most people are characterizing here.
1. Discipline takes training (preferably from a young age). If you practice overcoming those mental blocks, you will be more accustomed to doing them and recognizing and avoiding those escape behaviors that we call procrastination.
2. Visualizing and regularly reinforcing the Goal - that final benefit that puts all the work in between in context.
3. Planning/chunking the work. It's a form of gamification - but don't let it itself become a form of procrastination. 99% of people _already_ _know_ what needs to be done, right now.
Personally, I have a simple system. Three Google Docs. 1. Is a short, somewhat vague list of goals I revisit every year at tax time. 2. Is a list of projects in a rough order of priority (actually it's a folder of Docs with one doc for each project). ...and most importantly, 3. The daily journal, where I add to the top each day the date and a rough list of things I'm working on.
People get lost in making sure their prioritizing is perfect, or adding too many things to their daily TODOs. In fact, in the context of doing what's important, I find that one of the key skills is being militant about things you're NOT going to do - and ignoring requests from others that don't fall in line with your own goals.
