Even though majority of FT readers will not support me, with all honesty in your particular situation I would not worry too much about your travel rewards optimization and trying squeeze every possible benefit out of the system.

Being in a situation similar to yours in the past, I would tell you that getting most miles/points out of your activities is an interesting hobby but a pretty time-consuming one and you will most certainly be a very busy person very soon.

So get some rest and relaxation in your spare time (if you have too much of it consider whether you've chosen the right employer ) ). This is not to say you should not follow simple common sense - register for FF programs of all airlines/hotels you fly/stay and assign you FF # to your tickets/reservations once you purchase them. But if you're standing at a hotel's check-in counter thinking about what card to get out of you wallet to meet a spend or worrying about not getting your elite status renewed and considering a routing you would not otherwise fly, you went too far.

If you're one of those who cannot just have rest, spend your time going above and beyond in your job - your next big promotion will pay off much better than an extra 100,000 miles you could get.
