WRT to personal minima, discuss with your instructor, decide what they will be, write them down and STICK TO THEM. As mentioned there are planning minima, as in, I don't plan the trip if the forecast is less than X. And then practical, as in, you get to the destination and the weather is worse than X, what is the lowest reported, Y, that you will shoot the approach. They may be the same, they may be different. But if your practical minimums are 600 foot ceiling, if it is reported as 599, you divert. Another part is how many tries? If you go missed, do you divert immediately or try again? Do you try a thirs time? Personally, my planning minima are 800 feet and 2 miles. My practical minima are to attempt the approach if weather is report down to published minimums. The only time I would try a second approach is if I saw the runway environment as I went missed, but in general, it is one and move on.
Also what about your personal crosswind limits? I had a flight a couple of months ago where, when I took off there were gusts to around 30, direct cross wind at my home field, but forecast to lessen. But I also have 3 airports within about 45 minute drive that have runways that would have been almost direct headwinds.
Plan alternates along the route. If the weather is getting worse at your destination, stop before you get there. Less stressful and you can pick locations, planning on the ground before you leave, with the good FBO, hotels, transportation, maybe even commercial flights if you really need to get somewhere.
Consider StarLink. Giving your passengers internet access goes a long way to keeping them happy.
And the most important tip, to me, go to places THEY want to go to. At least to start, let them pick the destinations. They will put up with more to go where they want to go.
