these two are contradicting one another.
if you feel like you should "clone" another project then it means you don't really have a "great idea" in first place since you are basically copying another idea and want to make some changes that have been done a million times before.
not to mention that if you don't already know how to clone and build then your programming skills are questionable so maybe you have to start working on them before you think about creating a new coin.
