Not everyone likes you and that is absolutely fine. I used to be a people pleaser, desperate to be liked. Now I don't give a damn and am much happier.
If you want something, take action towards it, whether you feel like it or not. Don't wait to be in the mood for a run or in the mood to write a page etc. Just do it.
Find deep pleasure in small, easy things; free things: watching birds feed in the garden, dogs bouncing around a park, sunlight through the trees, a good busker, a smiley cashier.
Make rituals of small, easy pleasures: a great cup of fresh coffee in the morning, cuddling the cat, reading a poem or short story before bed, lounging in the bath, listening to your favourite band as you prep tea, watching comedy shows with your feet up on the sofa.
Make bucket lists of things big and small that you want to do and do them. Don't put them off.
Love your children. Spend time with them. Encourage their interests. Teach them and learn from them. I'd rather be less well off financially and see more of DC than have material wealth and be too tired to have fun with them. (I know those aren't the only two options but in my case, they were the choices.)
Decide what your own values are and live by them. I don't give a toss that our kitchen is ancient and out of date or that we have the uncoolest car in our area. I'd rather spend what money we have on travel and concerts and theatre shows.
