Just started cycling and went on my first ride with my 2010 Scott Speedster s30.
It's a 20 lb bike with Shimano 105 components so it's decent bike but I struggled to get up the hills.
It's only valued at $200 so I guess it's not a great bike.
Should I keep my bike and push through to get stronger or get an upgrade for better experience? Or upgrade parts?

If I were to upgrade, my budget is $1000 and I'm open to pre-owned bikes.
All suggestions are welcomed
