Try this - Leave home with nothing and go take a walk around. No bags, no phone, no keys, nothing. Just clothes and maybe $20 in your pocket for emergencies. Leave early and with no commitments later in the day. Eat on the road. Return when you feel like it. Walk at whatever pace you like. Go wherever your legs take you. It's an awesome feeling like nothing else. Helps if you live with someone so they can let you in…
For me, every time I do this, I get a feeling of contentment. I also feel inspired.
