If you’re stuck inside during most of the sunshine hours, take vitamin D! I take it year round and it definitely helps perk me up when I can’t get that sunshine I crave. For an even bigger boost, get one of those full-spectrum sun lamps. Mine lives on my desk at work and is totally wizard.
For the love of all that is holy, get your car brakes checked regularly. Once a year minimum, but twice a year if you commute in a lot of stop-and-go traffic. Paying for brake checks is a heck of a lot less expensive than having to replace everything around your brakes. Trust me. Do it.
