This will be a different advice from what you expect, but be thankful for all things you have.

Stop worrying about being more productive and making a lot more money. I'm not saying you shouldn't think about this things, but don't let worries about those things consume you and become your whole life.

Understand that on average you are living better than kings and queens did thausend years ago or even 100 years ago. Got a fridge? well be thankful for that. Got heating, a bed, bath, clothes, food that you like? you are living the dreams of billions of people who can't have any of it. Just be thankful for things before you want to get more.

Happiness is doing more and expecting less.
