Hey
A few tips :
1) Start meditating
2) Take a break – you need it . 5 years is a very long time . Go on a vacation , a retreat , or maybe a social sabbatical – just to refresh yourself socially.
3)If you however , feel that work indeed is really boring – start building a life that accommodates for both work and fun. A healthy mix is required and you might end up having fun at work – because you’re having fun when you’re off work too !
4) Please consider volunteering – it really does feel good
Cheers! 😀
