Catrin, are you planning to jog continuously for 60-90 minutes? IMO, that's a lot to bite off for a new runner. I had to build up for quite some time to even get to 60 minutes, and I don't think I'm atypical. Remember that you need to give your muscles, joints, ligaments, etc. time to adapt to running or risk an overuse injury--even if your form is otherwise good.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
