Becoming a software architect is a great accomplishment. However, you must seek to keep improving to excel in your role. You must continuously learn new things to increase both the breadth and depth of your knowledge. Reading books, taking classes, listening to podcasts, reading blog posts, and watching videos are all ways that you can learn new things.
Participating in open source projects, writing your own blog, teaching others, trying new technologies, writing code, and attending user groups and conferences are all ways you can continue to get better at what you do.
Stay curious, keep learning, and never stop asking questions. Have an open mind and continue to create new things. Always strive to make the things you put out in the world as good as they can be. Be a software architect.
