Tips for everday hairstyle please!

So I'm looking for suggestions on what to do with my hair as a daily routine to have a nicer look. I have long, somewhat thin, but overall healthy hair. I like my hair long, so not looking to change styles, but I would like to have a good hair day nearly every day. Everybody else always looks so put together and I just feel frumpy all the time lol. I usually do a side part, but my hair can't decide which side it wants to be on so sometimes my part ends up all over the place. My hair tends to be on the dryer side and tangles easily so I usually use a leave in conditioner of some sort, but I'm not sure what else I can do to "style" it while wearing it down and straight. (I do curls for special occasions, but by the end of the day my curls usually turn into a tangled up mess that takes all of my patience and conditioner to undo)
