I started the new year with decluttering by getting large plastic boxes and finally going to a local donation venue to give away clothes and items that were in good condition however that I could no longer use in spite of my progress in losing weight, last year, a net value of 20 pounds! Still, just can't wear the same jeans I wore in college or just after I had graduated. Yet before my weight gain occurred during the last two years of graduate school, 2016 to 2018, occasionally life could works its magic and I could get into dresses from ten years prior, go figure, so I kept those as a reminder and will start budgeting to go shopping eventually in the spring. The effect was a more organized closet space and a healthier mental energy from the process.
My recommendation is to try to declutter one room a day until everything is organized again and to give away extra items. Find your local donation venue, like goodwill for example:
