A great way to learn is through the internet! There are so many great (and free) sewing tutorials online. To start learing about sewing basics, I would recomend this channel. And for some fun, (but not as practical) inspiration, I would recomend this channel. The best way to learn is through trial and error, so I would recomend just setting some goals for yourself and then finding videos on how to accomplish them!
Once you have completed a goal, check it off your list!
