To make every working day feel like weekend, I have a tip: I add “padding” to all deadlines. This may not be an option for everyone, but I myself always add a little padding to every deadline. For example, if I think I can get a project done in 2 weeks, I’ll say I get it done in 3. This allows for those unexpected setbacks to happen (as they always do), without messing up my timeframes and adding stress to the project. I can work without having to worry about the deadlines.
Furthermore, I create inspiring work environments. My work day will be more enjoyable if my work environment is pleasing. Little things like having good coffee or tea on hand can be soothing. A little mellow music like jazz, blues or classical adds that light, relaxed coffee shop feel to it.
