<prompt> Human: Hello rpersonalfinance!I am just starting out in my career at 26 and through sheer luck I have inherited 200k in stocks. I am contributing 5.5k each year into a Roth IRA and as soon as I get a full-time job I will put in as much as possible into a 401k as well. My goal is to convert the bulk of this to retirement funds.Lately I am starting to freak out when I read news headlines about wealth inequality, the terribly economy, etc. in the sense that I dont know if I have faith in stocks and mutual funds to be a reasonable investment for the next 40 years. This fear is completely irrational and based on emotionally reacting to sensationalist news reporting, but nevertheless I am nervous.How do you guys stay calm and stay the course? I know nothing is guaranteed but there has to be a way to be feel better about investing long term.Assistant: Simple, Im not irrational and I dont watch TV.Human: I dont mind condescending answers with actual substance, but this isnt helpful and you are most certainly irrational to some degree, as all humans are. Do you have something constructive to add? I see you post here a bit so am genuinely interested.  <response>: Heres what you said:Lately I am starting to freak out when I read news headlines about wealth inequality, the terribly economy, etc. in the sense that I dont know if I have faith in stocks and mutual funds to be a reasonable investment for the next 40 years. This fear is completely irrational and based on emotionally reacting to sensationalist news reporting, but nevertheless I am nervous.You then asked me how I stay calm. I said I dont watch television, because CNBC is garbage and people have lost a fortune with their inane drivel since there is no money in put your money into ultra low cost SP500 index funds for television networks. And I ignore irrationality. I dollar cost average into markets and keep a reserve cash fund so that when the market implodes and falls 7 in a day, I race to dump more cash into it to buy things at a discount.
