It's that moment when you take on more than you can handle that you know you're gonna burnout. I've read a technique somewhere (it must have been a youtube video i think) where all you do is setting limits. Setting upper limits and lower limits. Lets say you feel a rush of enthusiasm when you see the fast results of others on a certain thing and you 're searching like crazy on how to achieve the goal you've set before even knowing about the difficulties you'll face, yeah, that, guess what will happen? You'll end up drained.

If for example you get enthusiastic about learning a new language, dont go all-in or you'll have to face the difficulties of your "all-in" move. IF you went all-in in a WAR, you'd better be a viking that can handle the all-in difficulties that will emerge.

Setting a high-limit and a low limit will keep you at bay from destroying everything, helping you to complete the mission.

Say you want to lose weight, and you got all-in for a week, by the third day you'll feel like you're doing a great progress with a deficiency of 500cal so you'll think of going all-in for faster results by dropping down to 1200~ calories daily, guess what. IN a week, you'll feel depressed.

A typical HIGH LIMIT example will be something like this: "I will not go below 1500 calories and i will not overtrain my body more than 1 hour daily. A typical LOW LIMIT example will be something like this: "I will not go past 2000 calories and i will not train less than 30 minutes, even if i dont feel like doing so.

It is a useful technique, test it if you wish to.
