How to stay consistent with gym?

I've been going on and off from the gym. 1 thing I know for sure is that I gain muscle quite fast. The problem with gym is I'm not consistent with it. Last time I went for like 2 months straight but winter came and it got cold as hell so I didn't go. Going forward a few months and now I'm here. Having a lazy life style and going a few times a week and then skipping a few weeks. I always kind of get intimitated at the gym because I see so many people way bigger than me.
