As long as you practice daily, and enjoy it you should be fine.

I play an acoustic guitar and it's not hard at all. But I play by ear, I didn't have any lessons

There are loads or ways to learn guitar, normal lessons (this gets expensive) look on youtube (but its hard to suss where to start) or you can get a proper online course for very little spend (about the equivalent to the spend of one lesson with a real tutor)

Loads of tips and videos on here

Here's my advice to you.

Learn some basic theory. You should at least know the major, minor, pentatonic, and blues scales.

Set up a practice routine. Work on things like dexterity, finger speed, fretboard knowledge (practicing scales, arpeggios, chords, etc.). Practice, don't jam.

Jam, don't practice (doing both can help you a lot).

Learn other people's songs. Learning by ear can help you with your fretboard knowledge whereas only learning with tabs can hinder you.

Write your own stuff. Even if it's not so great at first it will help you with song structure and will be the building blocks of better material down the road.

Finally, learn different styles. Don't limit yourself to one genre. You'll appreciate being able to be versatile as you get better and better. Being stuck in a rut due to lack of musical exposure sucks. Trust me .

Good luck man and stick with it!
