Discipline is often painful in the present, but regret is far more painful in the future. The effort we avoid today doesn't disappear.... it returns later as missed opportunities, unfulfilled dreams and the question of 'What if I had tried?'

Every small act of discipline is an investment in the life we want to build. Stay consistent, even when motivation fades, because temporary discomfort is a small price to pay compared to a lifetime of regret.

Choose discipline today, so you don't have to live with regret tomorrow.

The gap between what we want and what we achieve is filled with consistent effort, dedication and discipline.

We all have dreams, goals, and aspirations but wishing for them alone is never enough. Every day presents us with a choice... we can continue procrastinating, making excuses and staying within the comfort  or we can stay committed to our goals with dedication and discipline

Success is rarely the result of a single big action. It is built through small, consistent efforts repeated day after day, even when motivation is low. The decisions we make today shape the reality we live tomorrow.

The distance between our dreams and our achievements is not measured by luck or talent alone... it is measured by our willingness to stay dedicated when the journey becomes difficult.

Our future is determined by what we consistently choose: comfort or commitment.

3️⃣ Dive into Hashing
– Use HashMap/HashSet for fast lookups
– Problems: Longest Substring Without Repeat, Group Anagrams

4️⃣ Linked Lists
– Learn traversal, reversal, cycle detection
– Key problems: Detect Cycle, Merge Two Sorted Lists

5️⃣ Stacks & Queues
– Infix to postfix, parentheses validation, monotonic stack
– Problems: Valid Parentheses, Next Greater Element

6️⃣ Recursion & Backtracking
– Subsets, Permutations, N-Queens
– Key skill: build solution tree and backtrack correctly

7️⃣ Binary Search & Search Problems
– Classic problems: Search in Rotated Array, Koko Eating Bananas
– Understand upper/lower bounds

8️⃣ Trees & Binary Trees
