To be successful lies in our own hands, its only when we see it a responsibility that we need to see changes in the way of life in which we are leaving and how we are putting more efforts in seeing this come to pass, being successful is not that hard to achieve, we can make it just as others did, when we give it all that is required form us, the same way others are working on something tangible without wasting of their time.
The first is clearly from ourselves, but it must be remembered that we live to need each other and, of course, there is nothing wrong with help from others can be accepted and is not something bad. Always remain optimistic that everything happens, because in the end it is from our own abilities and what is clear, as you said is also because of the hard work we do, but everything is finally difficult to avoid certain things that help from others is also needed and required at certain times.
Help can happen, but it is returned to us, because in the end everything can succeed because of what we have done with all our hearts.
