1. Take some good vacation or go work in a new country, I've been doing this for 5 years, visited a ton of country, even went to Africa, it'll definitely help you to kill the routine and appreciate your lifestyle.
2. Find a new working schedule, try working in the morning
3. Do a lot of stuff that doesn't include a screen. I do a lot of rock climbing (that's my favourite, specially when I really feel overwhelmed), running, squash, gym, etc..
4. Find some partners to work with in some office, it'll help you a lot to keep your grind and stay motivated in the same time
5. Make sure you have some time without any technology every day/week.
Keep it up man!
