For me, hodling means keeping your bitcoin until you really need and then selling, but only as little as possible.
Also, since I got into bitcoin, I always had some imaginary bitcoin pirce that I was sure will make me sell everything that I have, but every time we reach that level (10k, 50k, 100k etc), I sold only a fraction of it, and so far it proved to be a winning tactic.
Regarding hodling bitcoin forever, I see no point of it because bitcoin is money, and what's the point of money if you don't use it?
The primary purpose of every investment is to get profit that we can use to improve our living standard. Hodling Bitcoin is good for long term but not forever because the profit will be of no use if we are getting it in our 60s or 70s. I also see no harm in selling some of your Bitcoins when we need funds because that's what we are investing for. Sell some of your Bitcoins to generate necessary funds rather then going to Banks for loan. Moreover life is short and we don't know when we breath our last, so it's better to plan our hodling strategy accordingly.
