"Success" can only truly occur internally, because it is based on your emotional commitment. At the most basic level, success is your relationship with yourself. Most people are living a lie; either saying they want to change but not doing anything, or saying they want to live a certain lifestyle but then living a different one entirely. They purposefully ignore and distract themselves from what they deep down want for themselves.

Most want more for themselves, for their goals, and for their career. Yet, few of these people ever achieve what they intend to achieve, even in a single project. Each project adds up to the sum of your career, and so the long-term goals remain as goals.  
Being ambitious isn't enough. Far more important than ambition is commitment on a daily basis.

When you're committed to something, you will be and do what is required for the attainment of that thing. You'll stop wondering and start building. You'll stop being distracted and start learning. You'll start connecting. You'll start failing. You'll get what you want, rather than have a long list of "ambitions." You'll have actual accomplishments that reflect your inner goals and values. Don’t make your New Year’s resolutions and then let a year slip away. Pursue your project goals through having working goals, setting up your environment for success, and creating a growth mindset.
