I had a similar experience and concluded that the most important thing is to learn to drop as many things as possible. If the list are getting too big it just means we are trying to do too much. The objective should be to trim those list down as much as possible. Too many someday/maybe things? Well, time to decide to move them to never/surely not category (i.e. delete them or put them in the "won't do" category). Too many things in the TODO/Next/...? Well, it's time to think whether they absolutely need to be done. If they really, REALLY do, do they need to be done by you? Delegating, asking someone to do them or just externalizing them to some service can be a possibility. Focusing is not as much about deciding what to do as to decide what not to do. I know, they are logically equivalent things, but the main issue is that most of us are not psicologically well prepared to accept that we just won't do many things we would like to do, so we invent complex systems to keep track of what we won't have time to do and unnecessarily stress us in the process. Learning to just let go is one of the most useful things I learnt in life.
