True.
But it seems to me like we, very frequently, take comfort not in relaxing, but actually in being tired. This is especially conspicuous with males and the socially perpetrated image of a man sitting in an armchair after work, reading a newspaper... If we think about that, this image is so ubiquitous that we are almost certainly doomed to replicate it. If you think about Homer Simpson or Petite Nicolas' Dad, to 'be tired' was an undispesable characteristic of being a man.
What this means these days is that you come back home and waste time online. As a result, you fall into a vicious cycle of depressive states: you're frustrated because you waste time, and the more frustrated with yourself you become, the more time you waste.
The solution is not simple and it includes breaking old habits and building new ones. Start by not eating in front of a TV, computer, tablet etc. The destructive process I frequently follow is:
1. I'll go on Youtube while I eat
2. I finished eating, I'll watch a couple of more videos (after all, I'm tired: I deserve a break)
Reading books is better but not perfect. Try and focus on the eating or on a conversation with someone you live with.
Then, ask yourself: 'am I tired?' If you are, go to sleep. If you're not, do something productive. It will make you feel good.
It's not easy, but it's possible.
