If you have a seemingly endless mountain of problems, solve one. Pick the one that bugs you the most. Let everything else fall to the ground.
Deal with your one task until it’s under control. Not perfect, just under control.
Then move on to the next one.
When all facets of your life are functional, then go back and start leveling up each part one at a time. But first–make sure there are no fatally dysfunctional aspects to your life.
This is far more likely to work than the usual “whack a mole” deal of trying to solve a bunch of things all at once. You never end up solving anything, and you’re stressed out the whole time with no sense of accomplishment.
At least if you tackle one thing and solve it you can say, with pride, “I done this.”
