If I could go back in time and talk to my 24 year old self (besides offering some prescient stock tips!) here is what I would say: be prepared for your taste to change. Because I think personal taste is always evolving and at least for me, it can be a little disorienting since it makes me doubt all my other decisions — ie “if I was wrong about this, what else have I been wrong about” type of thinking. It takes a lot of confidence to just accept that your taste changes, just as you change (everything changes) and that is probably a good thing.
A perfect example is the shower curtain on the right. I bought it five years ago and loved it. I thought it was the height of sophistication. Today, the shower curtain on the left is perfectly my speed (for now). They are pretty different, right? Almost scarily so.
Other things I would have told myself:
Enjoy your skin, thighs, hair, boobs as they are right this minute. (Aging is a long, slow, horrifying process).
Get a library card and use it (seriously, this is probably the first thing I should have said to my book-hoarding 24 year old self).
What would you tell yourself 10 year younger self?
