Even people that start with a nice platform have a hard time resisting the temptation to individualize! I started with accessories then wrecked the bike and replaced the accessories with new ones where many others start with performance mods which I may add in the future.
The point is that if you feel the urge to mod than mod till your budget (or your spouse) restricts you! This tends to be easier to manage for people with limited hobbies...
Note that if you don't plan on keeping the bike your mods should be removable or you should be ready to face the fact that they don't do much to increase the value of your project.
