I'm constantly very busy, but agree with boogieboogie. . It's all about feeling content within yourself, and getting your priorities right. My family come first, but work and leisure time often involve them anyway. I'm happy for it to be like this, so if you're happy and content in the first place, then everything else just slots in.
By the way - good luck to you. You seem to be on he right track. If you make time for the things you enjoy, you're going to be able to tackle the rest.
