Stay in school and get your ologies.
Have several strings to your bow - more than one thing you can do to earn.
Don't put all your eggs in one basket - your employer is not your friend and owes you precisely one month's wages and whatever pension.
Don't breed with a man who won't marry you.
Don't stay with a maybe baby man who dangles the mirage until it's too late for you.
Don't give up your job, income, savings, pension, to look after a man's house and children - you're an unpaid servant, aka a slave held in servitude by a misplaced sense of loyalty.
The much older man may have seemed exciting and sophisticated in your 20s - it will seem very different in your 50s.
Stay away from husbands and fathers - do not steal, wreck, destroy.
The first whiff of infidelity, coercive control, violence or fetish behaviour - get out. It will get worse.
Fix it early - the toothache, the pain, the lump.
Go to your checkups and catch it early so it can be treated.
