Sponsored posts and affiliate offers seem like no-brainers if lifestyle / e-commerce is your goal. Depending on your ability to convert clicks > sales, you can formulate strategy around developing your own set of sites to benefit from the traffic.
There are definitely opportunities to think bigger (really, ANY idea can benefit from substantial / targeted eyeballs), but starting with sponsored posts / affiliate would give you an easy and instant monetization opportunity.
Just sign up to a few advertisers at CJ that align well with your niche to test it out.
