Muscle soreness when you first started working out is normal because your muscle is suddenly sent into shock from the sudden workout.

Overtime your muscle started to get used to it and the soreness went away. It's completely normal. It doesn't means you aren't making progress.

Don't worry, keep going

It means adding weights progressively after each successful session.

Also, don't do that. Muscle imbalance is a real issue.
It's recommended that a beginner starts by doing compound exercises (Exercises that use more than 1 muscle group) as you can lift more weights and train more muscle in one session.

Find a good program and follow it.

Not everyday.... You need to rest one day before hitting the same muscle group again.
Your muscle needs to rest so that it can grow properly.
Overworking will only induce injuries...
