I found myself in a similar situation (after 20 years of work, though, so my expected remaining lifespan is probably shorter). While I did invest most of it, raising means is only half the job. The other half is lowering needs. This is already how I managed to save most of my pay each month, but the older I get, the more extreme I take it. Not only does it ensure my stash will last as long as it needs, but I acquire lot of new skills on the way (by learning how to build rather than buying). Oh, and I don't have a family, it probably helps a lot.
