I prep my family meals and make double matches and freeze some.
For me since my tastes are very plain I can easily get IP ready fast.
When going to work I carry 1-2 days worth of packets ,Tuna in a packet,whole cucumber,Red Pepper,and always have a peeler in my Backpack.
Grab my Shaker and Insulated bottle with Black Coffee.
Also have Teabags for hot or Iced Tea.
Sometimes I think we can over think things,I can have my food ready in 5-10 minutes that includes the time it takes for the coffee to brew!
I'm a procrastinator my nature so I work better under pressure.
Don't waste your time worrying about a bell that can't be unrung ,use it as a teachable moment.
There are enough people in the world that will beat up on us ,lets not do it to ourselves.
Sometimes I believe we learn more my are mistakes then we ever would by not making them.
Be proud on yourself of what you have accomplished so far 3 weeks OP

Good Luck and give yourself a Do over!
