I enjoyed the responsiblity and maturity of having to work for an income, especially as it get recognised and opens chances for promotion.
What I wish was different
I learned that I could probably be up to more days per week,possibly with a break in the middle of the week, but the job taught me to look for more opportunities.
Advice
Keep a disciplined routine and timetable: get up on time, go to bed on time, eat and wash on schedule.
