If you want to get better faster, use a metronome. A metronome either clicks or beeps a consistent beat that you play along with. It helps develop your sense of rhythm and helps build your muscle memory as you practice.

The simplest metronome is a ticking clock, which beats (ticks) 60 times per minute. Try strumming the G chord to this beat. Try to be exact and time your strum precisely on each beat (tick), and you’ll get an idea of what its like to play along with a metronome.
