I need money 💔 my phone die

Selfless.

Why someone with gold membership regularly visits your profile (sometimes twice a day) but don't match.. Why is that? Is this because of limited profiles available here?🤔

Hi what's up guys how are my all people. I hope you all are doing well. How much happy you are with your parents here hmm ??

Week 8 complete — 42 lessons, 244h of tracked study, Day 110
SQL. This week was subqueries — a query inside a query. I learned the three shapes and the rule that picks between them: run the inner query alone and count what it returns. One value → it goes in WHERE, after an operator (=, >, <). One column with many rows → it goes after IN. Rows and columns → it goes in FROM, and it must be given an alias.
This is mid-level material, and IN was where I struggled. Partway through, I refused my own lesson's "complete" verdict: I had followed the instructions and produced the right outputs, but I could not rebuild the queries unaided, and following instructions is not the same as having learned something. So I sent myself back through the topic before moving on. That redo is what found the real gap — a rule I had never learned: an aggregate used in HAVING does not have to appear in SELECT. HAVING evaluates its own aggregate, so it can compute purely to filter and never display the result.
One habit came out of the week: I started proving answers twice instead of once — the same total reached by a JOIN and by IN, then checked by hand on a calculator.
One task needed a count for every location, including the ones with nothing to count. Two things can go wrong there: inner join drops the empty ones entirely, and count (*) turns their zero into a one. I tried both forms of COUNT and kept the one that produced the zero I already knew should be there.
Excel. In my Week 7 post I wrote that XLOOKUP was the skill that stumbled in my first cold simulation. This time it ran clean, from cold, with the right arrays and absolute anchors. I also rebuilt a full Power Query pipeline on a messy readings table. Data Validation moved to Comfortable. Advanced Filter is now 3.5 minutes, down from 18 minutes in May.
IELTS. Two of my weaknesses moved to Solid: subject-verb agreement and run-on sentences (comma splices), both on timed evidence. My first General Training letter since May came in at 6.5, up from 6.0: 151 words in 22 minutes, including a two-minute proofread pass that I now run on every timed piece. For Task 2, the constraint is speed rather than knowledge — planning and body-paragraph writing.
For the record: these posts are drafted with Claude's assistance, in my own words. Everything in them is true, and it happened.
Learning has become intrinsic, and I still feel I could do more. There are also times when I think that doing all of this for myself alone is not enough. To my mind, people are made to work for more than just themselves. That is part of why I keep going, and why I treat my physical and mental health as seriously as the studying.
I work a 24-hour shift every three days in the oil industry in Baghdad — this is how I'm building toward a data analyst role abroad.
