If I understand you correcctly, you're asking two questions--what stuff should you do, and how should you make sure you keep doing stuff? Just to answer the second question first--sinking money into something is a good way to motivate yourself. So--for example--take advantage of London's great theatre. Buy yourself two tickets for a show two weeks for today, and then find somebody to go with you. (Note that this technique seems to work best for specific, one-time expenditures. If you pay for a year's membership in a gym, the expense will keep you going for a few months, but at a certain point, the money will fade away into the past and will cease to motivate you.) Another good technique is to commit yourself to somebody else. Agree with two mates that you're going to (say) meet every Sunday and go for a run. Now if you're not going to make it, you're going to have to call them and explain why. And then there's public commitment. You've stuck to writing this blog, haven't you? Presumably the fact that the world will notice if you stop keeps you going. So, whatever your goal is (one social event a week? A workout every other day?) announce it here, and promise that you are going to update your readers every week on how you're doing. For maximum effectiveness, combine all the above techniques. Agree with three mates that you're going to run every sunday. Anybody who misses a Sunday has to put £5 in a jar. At the end of the year, whoever missed the fewest Sundays gets the contents of the jar. Post the running jar tally--along with your contribution to it--on the webpage. The contribution jar idea does work--or, at least, it did for me. It was the only thing that got my roommates and me to stop skipping classes in our first year of college.
