What do other mathematicians do if they get "in a rut" and feel like they're losing motivation? I'm a 4th year MMath student in the UK and this term I'm taking courses in Stochastic Analysis, Differential Geometry, Brownian Motion and PDEs. I'm also supervising 1st year students (4 hours a week plus planning and marking work) which I'm getting paid for and quite enjoy (except marking) but it takes time. Also I need to start work on my 4th year project and possibly apply for a Phd... I find that after I get home (after 5 most weekdays) and finish marking first year work I'm quite tired and lack the motivation to work on example sheets, read lecture notes or do research for my project. Often if I start something I'll get distracted or give up if I can't do it quickly. Obviously leaving these things until the Christmas holiday is far from ideal. I'll probably be taking one fewer course and have a little less marking next term but I'd appreciate any advice for keeping up my motivation and making the best use of my time. There's hopefully no significant chance of getting less than a first class result given I have 90%+ for my first 3 years but I should really be enjoying the material and it shouldn't feel like such a chore... Thanks for any replies.
