As for working for your dream company I think you should try to get there. Wouldn't want to regret it your whole life, as it can sour your relationship even with the best job you have now. As in it is better to be disappointed.

I think this advice needs to be more complete. Here is my attempt:

Change jobs every 2 years to increase salary (can be in the same company). Deal with all types of bosses, while learning what kind of boss you need. Keep in touch with bosses you liked.

Once you are ready to settle down maintain this strategy until you hit a wonderfull boss, then start growing more laterally and try yourself at this whole one company career knowing that you are supported.

Trying to settle down with a good boss too early can be problematic. Your great boss can't really help you with a salary boost, because that comes from up above corporate anyway. You also are limited to what you can learn about other companies, bosses and yourself.

It's very simillar to dating, know when to move on, know when to settle down before it's too late. Unless you want to be a freelancer. No judgements, it can be very fun too.

In the words of Demi Lovato interview:

- What's your favourite dish?

- I like mugs, they are great for holding hot things and have a handle.

At this point let's just attach a dynamo to Louis Rossmann for infinite energy.
