I realized my biggest weight reductions. By studying others gear lists.(checkout phats above it helpd me) and understanding what I could live without or getting multiple use out of.
And for the most part I do remain under 20 pound base weight with. A rather large three person tent for my wife,myself and our two kids.

I also carry all of the cooking gear for them as well as my kids sleeping bag. Simply by not bringing anything I do not I repeat do not need.

You don't even want know what my base weight is for a solo hike these days its sick.

Minimalization is the key in my opinion.

I will say goodluck to u sir and remember to have fun and enjoy your trips a few extra pounds will only make you stronger.
