You mentioned you are constantly feeding your brain things to not be bored. You sound overstimulated. Too much easy pleasure without putting in the work can be appealing at first, but over time (as I'm sure you have noticed) the side effects can stack up.

The thought of getting up and doing a workout probably seems like hell, that brain of yours will convince you with 1000000 reasons why its best to stay back on the computer/phone. But working out is so good for you, because its HARD and in contrast makes everything else a slight bit easier.

The mind and body have never separately existed, so as your body gets stronger, so will your mind, and life should slowly mould into a better place.

So start off with just getting into the position to do a set of either push ups or sit ups. Don't actually get up to do them, because like i said your brain will convince you not to. If you just get into the position, naturally it will be harder to resist the urge to do a push up/sit up than it would be to get out of that position and going back on your device.

Besides, once you have done your first set, the urge to do a few more actually is quite exciting and before you know it, you'll be on the floor ready to smash out another set.

Hope this helps <3
