This is a good thread to see.
@Fruitbat I feel you on the inheritance thing. I too had to make it on my own but surrounded by people whose families never worried about money; had plenty, had help with a car or a house or a trust fund etc.
You cannot dwell on it. However you can help your children a great deal by letting them see the toil sometimes, let them know its too expensive or we can't aftord it. Let them see the bills. Be honest. Be transparent. About everything. Exercise discretion and age appropriate content of course but let them see. Be human, mistakes and flaws and all. Your children will see what authenticity is. If you can show them that they will come to respect your humility. Love them but parent. Listen & coach and prune/monitor/influence the peer group like a hawk, but a covert hawk.
You can be friends after they grow up. As children and young adults you must guide them, and parent them and they will not always like you in the moment but as they mature they will appreciate you steering them properly.
Just today I was explaining to my 15 year old the importance of high grades. Why? Because the higher her GPA the more options she will create for herself. Its about HER and in US it counts beginning in 9th grade. This past weekend I took her to an event attended by prominent people in the field she wants to pursue. She went up to influential people, politely introduced herself, networked and asked questions. Of course people like this kind of spunk & initiative. She received inspiration and observed success. Why not me? She says to herself.
Let them screw up, let them fail, hold them accountable. Teach and require good habits: thrift, tidiness, not to put things off, chores with a good attitude.
I tell my kids straight: The world couldn't care less about you. The world cares about your results and will make judgements about you based on those results. Your family loves you but youth is a time of innocence/love/fun and as you are a teen, its training wheels for real life.
My kids (2 are launched from the nest) are hardworking, responsible and caring people. They know a deep sense that mom & dad aren't perfect, but mom & dad love them and will advise them & help where we can.
My kids have groundedness and gratitude but are all in active pursuit of their dreams. They are good human beings. Its humbling to see your children that way. It makes all the hard bits meaningful.
