Short-term vs Long-term

Assuming I continue the progressive loading on my lifts, within the next two weeks, I'll be doing PBs on all four. I currently weigh just under 80KGs, and will probably weigh around 82 in x2 weeks time. 7KGs lighter then the last time I was doing PBs. I've put on about 3 or 4KGs already this year, and my waistline has expanded incrementally. I am having trouble fitting into all my jeans and trousers in the legs area. I think this is partially muscle growth, but also fat storage. I also feel as though my arms look bigger. Again, I think this is partially fat, and partially muscle. Trying not to be so short-term focused but it's tough not to be. I just need to keep my eyes on the long-term - 130 Squat, 90 Bench, 160 DL. Don't have an overhead target, just progress as I can.
