If the temperatures are in the 30's or above it is pretty easy to put on enough layers to be comfortable walking. I know the feeling and have empathy for initiating the getting out part. Thankfully I have been walking for so many years I KNOW it will warm me up, energize me, make me much happier when I do finally get out and after I get home again. Sometimes it is wise to just decide you will go and then do it whether or not you feel motivated.
