<human>: Give me the gist of the text in a nutshell

**Background**
I am a 35 year old physician who has an undergraduate degree in finance.  I am married with two children.  I potentially "know enough to be dangerous" to myself and my family, but I can read financial articles/information and generally absorb the details.  My wife and I don't have a formal budget.  We spend too much, but are not going into debt, we just aren't saving as much as we should

**Assests**
Home equity of about $70K  
Retirement accounts (Roth, converted IRA, 401K) totaling about $60K  
Investments (currently 100% stocks, reasonably well diversified) - $130K  

**Debt**
Student loans of about $60K  
Car loan – $15K  

**Questions**  
1.  At what point should I hire a financial planner to make sure that I'm not on the wrong path.  I don't want to assume that I am doing things correctly, but I also don't want to spend money on something that I don't need, and I also need to make sure that the person would have a better plan.    
2.  When should I diversify from all stocks?  At some point I'll need to diversify from 100% stocks, but I could probably lose all of my saving and still do reasonably well in terms of earning wealth to rebuild.  I'm risk tolerant and understand market fluctuations.  I don't expect to need any of my current savings in the short term.  
3.  How important is it to have a "formal budget."  We've tried, we always get bogged down in the details, and end up doing nothing.  Is it "OK" that we are not formal in our spending?
<bot>: I am some background in finance, our family is doing reasonably well but I am not sure when to get expert help to make sure.
