As someone who has lost ~95lbs in the last year or so, and about 115lbs from my heaviest weight, I will say it has not brought any benefit other than endurance and self satisfaction (although to be fair, I only interviewed after losing ~20lbs and not since). Any goal is achieved through, first and foremost, setting that goal. The next step is to identify and try something towards achieving that goal, measure the success or failure, and either make it better or add to it (success), or try something else in the case of failure.
Humans are not very good at achieving great success with more than one goal in focus. Yes, you can have success, but your greatest success will come when it is something you want more than anything else and it is all you focus on. So, if I were you, I'd focus on losing the weight simply because it will be something that impacts most anything else you will want to work towards. It will improve your outlook on life and mental attitude, thus increasing the impact on any other goals you set thereafter.
Losing weight is not all that complicated, it takes patience and persistence and most of all - determination. EVERYONE knows the "secret" to losing weight - diet and exercise. It's the determined that execute the "secret".
