Your choice. If you feel it's not holding you back then go for it.
IMO, pot is great when you're stuck in a situation in life which you can't escape for other factors. It can make a bad situation tolerable.
IME, pot increases your tactical thinking skills while reducing your strategic thinking ability. For instance, I spent years as a programmer doing well in my job while I was high all the time. It was great during the early phase of my career when people didn't expect much out of me, other than solving a list of bugs/defects or hacking my way through things. When I 'woke up' in my 40s, I realized I failed to grow in ways that were necessary for me to advance as both a programmer and a person. Now that I have spent some time sober, I really see what it enabled me to do to myself(or not do).
If you haven't taken a 6 month break I highly encourage it. If it seems difficult I hope you are honest with yourself to the point where you realize the hold it has on you. I spent 15 years nearly constantly high. I always told myself I could quit and never managed to go more than a few days sober. I always told myself that I just didn't want to stop, but I could if I really wanted to. It wasn't until I really tried to quit that I knew the kind of hold it had on me.
I think a lot of us in the tech industry can get away with a lot of bad behavior for quite a while. Showing up late, or stoned, or both... Not pushing the boundaries but just getting by... A lot of us can do that and still be considered 'rock stars' by the people around us, but therein lies a danger.
I'm not saying you can't smoke pot regularly and be successful. There are always exceptions and people with enough willpower to make it happen. They are the minority in the people I've encountered in life, however.
