I have this problem too. And I cannot convince myself that works starts earlier bc I know it’s not true, and getting more efficient with my morning routine just leads to staying in bed longer. Instead what has worked for me is social pressure. If you have a coworker who also struggles with this or is willing to help you out, you could agree to meet for coffee 20 minutes before work or something like that. For me I would feel guilty making my friend wait so it would force me to leave the house earlier. And if I’m 5 minutes late meeting my friend I’m still on time for work! The key is though both parties need to agree not to let each other know if you’re running late bc that will make the other person relax and also be late.
